Pros : Lead free.
Cons : My gripe with this solder is that you read all over in literature, books and the web how great this solder is in terms of shine, flow, etc. I find that it flows poorly, does NOT shine and does not take Novacon patina as well as I would like it to. Also, that it has silver in it is questionable being that silver melts at 1763F. Maybe it does have silver. I have never found any literature stating that it does contain silver as in real silver. I have used other brands with far better results. I have used much less expensive with the same results. In short I bought this for the shine and it never shined for me.
Other Thoughts : I do not think I will ever buy this again, unless I find a way to make it shine. Polish does not help.
